| Principle of Coating Anticorrosion |
| None-Electrolytic Zinc Chromate is a new system of metal anticorrosion. The primary method of coating againstis: The main rustpreventive mechanism of this coating is: zinc has acontrolled electric chemical protection effect on basic parts. Zinc,aluminium and chromate acid compound have machinery shielding protection effect.Elutriation effect from aluminium restraining zinc. |

| Structure of The Coating |
| To coatting a layer of Non-electrolytic zinc chromate on the metal surface ( Namely contains Zinc flake with rang of size between 0.1~0.2*10~15^m,CrO3 and special organic of high dispersiod composite water base solvent),Some time after being cured under about 300 degrees, Cr6+ change to Cr3+. Then there was chromate acid compound coating on the surface of the basic material, and coating between zinc and aluminium. after cooling, to coating the metal surface with 6~8^m Silver-gray special high corrosion resistance of Non_electrolytic zinc chromate. |
